Complete Guide to Access Mini Greenhouses
Why Choose an Access Mini Greenhouse?
Access mini greenhouses stand apart with genuine toughened safety glass rather than standard horticultural glass. This 4mm glass is five times stronger than regular glazing and won’t shatter into dangerous shards if broken. The architectural aluminium frames carry a 25-year warranty, with powder-coating options available in green, grey, or black for 10–15% extra cost.
The unique sliding panel system provides ventilation control that fixed vents simply can’t match. You can adjust airflow to the millimetre, preventing the dramatic temperature swings common in smaller growing spaces. This precision matters when you're growing delicate seedlings or heat-sensitive crops in just 6–12 square feet of space.
UK manufacturing means faster delivery times (7–10 days for standard aluminium finish) and access to direct manufacturer support. Unlike imported mini greenhouses, Access models are designed specifically for British weather conditions, with reinforced glazing clips that withstand typical wind speeds of 50–60mph.
Finding the Perfect Spot
South-facing walls capture maximum winter sun and can maintain temperatures 5–8°C warmer than ambient. This positioning extends your growing season by 4–6 weeks at each end. North-facing installations work well for shade-loving plants and summer salad crops that bolt in direct sun.
Lean-to mini greenhouses attach to any sturdy vertical surface. Brick or stone walls are ideal, but timber-clad walls work fine with proper mounting brackets (included with all models). For balcony installations, check your floor load capacity — most Access mini greenhouses weigh 35–55kg fully assembled, well within typical balcony ratings of 250kg/m².
Freestanding models like the Exbury need level ground and protection from prevailing winds. Position within 10 metres of a water source and 5 metres of power if you plan to add greenhouse heaters or automatic ventilation systems.
What Can You Grow Year-Round?
Spring (March–May)
Start tomatoes, peppers, and aubergines from seed 6–8 weeks before last frost. A 4ft × 3ft Access mini greenhouse holds 40–50 seedling trays on adjustable shelving. Remove shelves in late April to accommodate growing plants in 2–3 gallon pots or grow bags.
Summer (June–August)
Cherry tomatoes thrive in Access mini greenhouses, with proper ventilation preventing temperatures exceeding 30°C. Slide panels open during hot days to maintain 20–25°C optimal range. Expect yields of 2–3kg per plant in a 3ft × 3ft space with weekly feeding.
Autumn (September–November)
Extend salad season by 6–8 weeks. Rocket, mizuna, and winter lettuce grow through November in unheated Access mini greenhouses. The 4mm toughened glass provides better insulation than polycarbonate, maintaining 3–4°C temperature advantage over outdoor conditions.
Winter (December–February)
Overwinter tender perennials like fuchsias, pelargoniums, and citrus plants. Most survive in frost-free conditions (0–5°C) without additional heating. For active growing, add a 150–300W tubular heater from our greenhouse accessories range.
Key Features Explained
- Sliding Panel Ventilation: Infinite airflow adjustment prevents heat spikes. Crack panels 2–3 inches on warm spring days to maintain 15–18°C — ideal for hardening off seedlings.
- Adjustable Seed Tray Shelving: Four fold-away shelves on Hampton and Exbury models hold 24–32 trays total and fold flat when growing tall plants.
- Toughened Safety Glass: 4mm glass meets BS 6206 Class A standards and crumbles safely on impact, perfect for family gardens.
- 25-Year Framework Guarantee: Aluminium frames resist corrosion and UV degradation, with less than 5% colour fading after 10 years.
Installation & Accessories
Self-assembly takes 2–4 hours with two people and basic tools. Wall-mounted models use 6–8 masonry anchors (included). Timber walls require fixing into studs or a backing board.
Recommended Add-ons:
- Automatic Louvre Vents (£45–65): Temperature-activated, open at 18°C and fully extend by 25°C.
- Shading Kit (£35–50): Reduces internal temperatures by 8–10°C on sunny days.
- Mist Watering System (£55–85): Maintains humidity for seedlings, using 2–4 litres/hour from a garden tap.
